CAE 와 같은 고충실도 대용량 엔지니어링 데이터의 시공간 정밀 분석검증을 위해서는 고해상도 몰입형 가시화 기술과 더불어 이를 직관적이고 효율적으로 제어하기 위한 휴먼 인터페이스 기술이 중요하다. 최근 대중화에 근접한 HMD 기기 및 컨트롤러를 이용한 응용 연구가 발표되고 있고, 이를 통해 엔지니어 위주의 정적 분석환경을 벗어나, 설계/해석/운용 전문가들의 동적 협업분석 환경 제공이 가능한 몰입형 가시화 환경 및 휴먼 인터페이스 기술이 적용되고 있다. 하지만 CAE 해석지원을 위한 대화면 몰입형 가시화 환경에서 사용가능한 직관적 인터페이스기술에 대한 연구는 미진한 상황이다. 본 연구에서는 신체의 자연스러운 움직임으로 가상현실을 탐색하고 데이터 조작을 구현할 수 있는 몰입형 가시화 전용의 휴먼 인터페이스 및 연동기술에 대한 연구과정을 소개한다.

In this paper, a CORBA-based collaborative medical image analysis and visualization system, which provides high accessibility and usability of the system for the users on distributed environment is introduced. The system allows us to manage datasets and manipulates medical images such as segmentation and volume visualization of computed geometry from biomedical images in distributed environments. Using Bayesian classification technique and an active contour model the system provides classification results of medical images or boundary information of specific tissue. Based on such information, the system can create real time 3D volume model from medical imagery. Moreover, the developed system supports collaborative work among multiple users using broadcasting and synchronization mechanisms. Since the system is developed using Java and CORBA, which provide distributed programming, the remote clients can access server objects via method invocation, without knowing where the distributed objects reside or what operating system it executes on.

Up to recently, with the improvement of a computer power and high speed of network technology, advanced countries have researched a construction of the e-Science environment. As a major application part, a construction for environment of CFD, also, have studied together. During the research, people realize that not sharing hardware but also appropriate software development is really important to realize the environment. This paper describes about a construction of a collaborative research environment in the KISTI: Clients can connect to the computing resources through the web portal, run the Cactus simulation.: According to the computing resources, the simulation can migrate to some site to find better computing power.: Result of the calculation visualize at the web portal directly so that researchers of remote site can be share and analyze the result collaborative ways.

현재 대형 디스플레이는 여러 공공장소에 설치되어 장소의 목적에 맞는 정보를 제공한다. 이러한 대형 디스플레이는 가까운 미래에 더욱 많은 장소에 비치되어 사용될 것으로 기대된다. 또한 사용자와의 인터랙션을 통해 개인화된 정보를 제공하거나 원격지에 위치한 디스플레이 간의 상호작용도 가능할 것으로 보인다. 최근 대형 디스플레이로 고해상도의 타일드 디스플레이가 관심을 끌고 있다. 그러나 타일드 디스플레이는 분산 환경 시스템을 사용하므로 소프트웨어 개발의 복잡도가 높다. 본 논문에서는 분산환경의 타일드 디스플레이의 응용프로그램과 타일드 디스플레이들 간의 사용자 인터랙션을 통한 협업을 지원하는 확장된 iTILE 프레임워크를 살펴보고, 시스템 구조와 실험결과를 분석한다.

Bioworks is designed to make, visualize, automate and execute a model of biological analysis processes as a workflow in biotechnology field. It provides for constructing a workflow model of complex biological analysis processes more easily and reporting the analysis results of each step. Users can perform their analysis process by using a visuality and validation module provided as a plug-in program. It supports sharing their workflow in XML format, to which conversion is supplied by Bioworks, with Web Services to improve the efficiency of their study.

Recently, with immersive virtual reality(IVR) technologies, various services such as education, training, entertainment, industry, healthcare and remote collaboration have been applied. In particular, researches are actively being studied to visualize and interact with virtual humans, research on virtual pets in IVR is also emerging. For interaction with the virtual pet, similar to real-world interaction scenarios, the most important thing is to provide physical contact such as haptic and non-verbal interaction(e.g., gesture). This paper investigates the effects on factors (e.g., shape and texture) of passive haptic feedbacks using mapping physical props corresponding to the virtual pet. Experimental results show significant differences in terms of immersion, co-presence, realism, and friendliness depending on the levels of texture elements when interacting with virtual pets by passive haptic feedback. Additionally, as the main findings of this study by statistical interaction between two variables, we found that there was Uncanny valley effect in terms of friendliness. With our results, we will expect to be able to provide guidelines for creating interactive contents with the virtual pet in immersive VR environments.

Smart work, which is defined as work performed at home, satellite offices or with the smart devices to continually collaborate with the co-workers in anytime, anywhere using IT, is attracting much attention as an alternative work way to cope with the demographical changes of the low fertility and aging. Whereas some implementation cases of smart work have been considered as the success, the other cases have been reported as the failure to implement smart work practices. Nevertheless, there are few researches to identify the reasons of successful ways to adopting smart work. This study integrated the IT-based changes with the smart work practices to identify the critical success factors of smart work in individual, organization and industry levels. As the results, we found out the expected values of introduction, core elements of implementation, and industry characteristics to efficient adoption for smart work. Also, this study compared these evidences with the incumbent smart work policies. The contributions of this study is to develop the guideline to adopting smart work, the smart work implementation strategy and the improvement on the business process.
